Construction
Pd/Ag terminations are applied to the top and bottom of an alumina substrate. A resistive element is printed between the top face conductors,
which is then adjusted to value and protected.
A wraparound conductor is applied to join the top and bottom sides. The terminations are electroplated with a Ni barrier layer prior to plating with
a Sn finish.
Marking
Where space allows, LHVC resistors are marked with value in three or four characters. The coding is two digits for E24 or three digits for E96 fol-
lowed by one multiplier expressing the number of zeros. For E96 values on LHVC0603 standard EIA-96 codes are used, consisting of a 2 digit value
code and one letter multiplier code.
Solvent Resistance
The body protection and marking are resistant to all normal industrial solvents suitable for printed circuits.

LHVC Series
Flammability
The resistor will not burn or emit incandescent particles under any condition of applied temperature or overload.
Solderability
95% min coverage (MIL-STD 202F / 208H, 235C 2 secs)
Mounting (nominal dimensions in mm)
Packaging
The standard packing for LHVC0603, 0805 and 1206 is in 8mm wide paper tape, for LHVC2010 is in 12mm wide paper or plastic tape and for
LHVC2512 is in 12mm wide plastic tape. This is wound on a reel of 178mm diameter.
